Answer:
y = 2x + 3
Step-by-step explanation:
We need to find m and b
Let's input the first 2 points (3, 9) and (5, 13) into y = mx + b
9 = m*3 + b
13 = m*5 + b
subtract the first from the second
13 - 9 = m*5 + b - (m*3 + b)
4 = m*2
m = 2
Now let's input m = 2 into 9 = m*3 + b
9 = 2*3 + b
9 = 6 + b
3 = b
So the final relationship is y = 2x + 3
We can verify that the other two points (8, 19) and (11, 25) also conform to this relationship.

Answers
Step-by-step explanation:
since y=6x
by substitution
-5x+ 2 (6x)= -42
-5x+ 12x=-42
7x= - 42
divide both sides by 7
x= 6
y=6x
y =6*6
y=36
Given that (3, 2, -6) and (-2,5, 1) are solutions of two equations in a system of three linear equations, which of the following is true about the system?
Answers
Answer :
The system can be inconsistent or consistent and independent or consistent and dependent.
Step-by-step explanation :
Consistent system: When the system of equation have atleast one solution then the system is consistent.
Inconsistent system: When the system of equation have no solution then the system is called inconsistent.
Dependent system: When the consistent system have infinite number of solutions then the system is called dependent.
Independent system: When the consistent system has exact one solution then the system is called independent system.
We are given two solutions of two equations are (3,2,-6) and (-2,5,1).
But the system of equations have three equations.
Then, the system of equations may have no solution or may have altleast one solution.
If given system of equations have no solutions then the system is inconsistent.
If the given system of equations have two or more than two solutions then the system is consistent and dependent.
If the given system of equations has exactly one solution then the system is consistent and independent.
The system can be inconsistent or consistent independent or consistent independent.

PLZ HELP ASAP!! Given g(x)=f(x)+k, enter the value for k that transforms the function f into g?
What does k=
Answers
Answer:
k = -2
Step-by-step explanation:
firstly, let us examine the kind of transformation that we have
We have a transformation from (3,2) to (3,0) and (-3,0) to (-3,-2)
So, we are actually subtracting 2 from the values of f(x) to get the values of g(x)
This shows a vertical translation to the tune of 2 units in the downward direction
So, the correct answer here is that -2 is being subtracted from f(x) to give g(x)
Accordingly, the value of k in the question is -2

Answers
Answer:
x = ±1.155
Step-by-step explanation:
We need to graph the given function [tex]f(x) = 6x^2-11+3[/tex] and find its zeroes.
The attached figure shows the graph of the given function.
To find zeroes,
Put f(x) = 0
So,
[tex]6x^2-11+3=0\\\\x=\pm 1.155[/tex]
Hence, this is the required solution.

Answer:
(-1, 3)

In order for a point to be a solution to a system of equations, the lines have to intersect at that point in the graph. We can see that the two lines at the graph intersect at (-1,3), so that must be the solution.

Cole bought 10 gallons of gas at the gas station with the lowest price. He paid with two $20 bills. Write and solve an equation to find his change.
Answers
Answer:
$4.3
Step-by-step explanation:
Cole bought 10 gallons of gas at the gas station with the lowest price.(the lowest price is $3.57 each gallon.) He paid with two $20 bills. Write and solve an equation to find his change.
two $20 bills = 2 * $20
= $40
Gallons of gas = 10
Lowest price of each gallon = $3.57
Cost of 10 gallons of gas = 10 * $3.57
= $35.7
Let his change = x
His change = Amount paid with - cost of gas
x = $40 - $35.7
x = $4.3
His change = $4.3
